This unfortunate Mayfly, along with several of its companions, was caught in a maze of spider webs. The spider's constructive skill seemed to be timed to meet the arrival of the local mayfly population outburst.
In the early aquatic stages the mayflies are called Naids that feed under water. During the last aquatic stage Naids leave the water, molt and become airborne. Another transformation brings forth the adult mayflies. Adults have no mouthparts for feeding. Swarms of males fly up and down and seize a female as they mate in flight. In a short time eggs are laid on nearby aquatic plants.
Certain species of mayfly might live for only a day; others may live for 4 years as aquatic naids. There are over 500 species of mayflies in North America.
